High water pressure causing pipes to break?
I live in an apartment complex with polybutylene piping, and it has broken 3 times in 1.5 years I have lived there. The breaks are always in the same area, and the pipes also knock. I asked the apartment manager if he had checked the pressure because if the pipes are breaking that often then high pressure could be causing it. He claims the only way to solve the problem is to fix the pipes when they break. This morning I went and bought a pressure gauge and found the bib outside had a little over 70psi, is that high enough to cause a problem? Should a PRV be installed? If he continues to do nothing about the issue should I contact the county housing inspector?
